A TBI is an initiation device that utilizes a shock input stimulus where the TBI donor charge initiates and transfers a shock wave through an adjacent structural bulkhead with sufficient intensity to cause the initiation of a receptor charge on the opposite side of the bulkhead. The TBI provides a detonation or deflagration at the output end of the device without breaching the bulkhead which is designed to provide a pressure containment barrier post functioning.
What a thru bulkhead initiators can do
The bulkhead is intended to provide a structural barrier to prevent loss of pressure of downstream elements of the end item application. TBI outputs can be configured to fit the needs of any application by varying the design of the booster downstream of the receptor charge.
Where our thru bulkhead initiators can be found
The TBI, also known as a bulkhead initiator, is used in Arm/Fire devices, solid rocket motor ignition and applications where it is critical to prevent loss of pressure of downstream elements of the end item. The through bulkhead initiator is generally used where complete sealing is needed between explosive elements after firing.
Our TBI designs are qualified and used as a rocket motor ignition component on multiple launch vehicle platforms including NASA’s Titan II GLV. We has also created a TBI adapted for use in deep underground application where high temperature performance is critical.
